Platforms for Life is an innovative design-to-delivery system that tackles pressing issues in the North American housing sector — cost, performance, urban sprawl — while producing accessible and high-quality homes.
The system is part of a longer study in affordable net zero homes, conducted by Vancouver-based design firm LWPAC (Lang Wilson Practice in Architecture Culture) and Intelligent City, a leading developer in Canada.
LWPAC’s approach favours compressed laminated timber (CLT) as a material of choice to create modular units that incorporate diversity of use and form and are assembled into larger, more complex built forms.
Pre-fabrication and parametric design serve as tools to produce these variations that permit a response to site and programme, while enhancing speed and reducing cost simultaneously.
In place of the traditional ‘one-size-fits-all’ model, this adopts a scalable, bottom-up approach. The system’s proprietary software enables participatory design and mass customisation of apartments.
The housing units can range from micro-suites for individual occupancy to larger units for extended families. This flexibility in internal layouts empowers people to take charge and manifest their own vision of urban living.
The system uses a variety of distinct clusters developed through generations of prototypes. The units are stacked in efficient hallway-free layouts, fitting up to 50% more homes in the same footprint as standard housing models.
All modules have access to abundant sunlight, cross ventilation and outdoor areas through double-sided homes and open circulation. This helps to reduce the need for artificial lighting and ventilation by nearly 50%. The facade screens vary in appearance and opacity to control solar gain and privacy.
Social interaction spaces aid in community building within these clusters. The design also incorporates mixed-use forms to support facilities for urban agriculture, education, healthcare and recreation.
Platforms for Life is one of the first systems of its kind capable of rising above six stories. Its prefabricated modules can even offer seismic resistance on sites where this is a major concern.
Prefabricated CLT panels are used to create open spatial modules that are fire-resistant, highly insulated and can serve as carbon sinks.
Proposed as an end-to-end solution, the structure embraces a design-to-fabrication approach. Several scenarios are generated by the system’s proprietary software to determine the best fit.
This act of optimisation contributes to the manufacturing of timber panels used in module assembly through computer numerical control (CNC) machining and robotic fabrication, ensuring consistency and quality.
Here, automation and optimised supply chains reduce construction costs by up to 30% and construction duration by 50%. Cumulatively, these contribute to making the homes more affordable, even when built on high-value plots of land.
Moveable solar screens, full-height windows, geothermal heating and cooling systems and an airtight envelope result in energy consumption that is up to 90% less than the norm, contributing to a near net-zero performance.
Coupled with other performance metrics, the system’s projects are expected to meet requirements for a Certified Passive House design and achieve a LEED v4 Platinum rating.
In North American cities where affordable housing is hard to find, Platforms for Life is an innovative solution. Te project won the Holcim Award Silver 2017-18 North America for its scalability, affordability and exceptional performance.

A Frontline project is holistic, net-zero/net-positive and integrative. It protects or regenerates a combination of social, ecological, and economic systems, aiming for a ‘greater-than-sum-of-parts’ outcome.
There are no performance metrics available for this project.

Techno rozen For the reason that the admin of this site is working, no uncertainty very quickly it will be renowned, due to its quality contents.
Techno rozen You’re so awesome! I don’t believe I have read a single thing like that before. So great to find someone with some original thoughts on this topic. Really.. thank you for starting this up. This website is something that is needed on the internet, someone with a little originality!
Thanks for your context. Introducing A1 art, A1 Art is an AI-powered art creation platform designed to help users generate stunning digital artwork with ease.
The next time I just read a blog, I hope so it doesnt disappoint me about this blog I mean, It was my solution to read, but I personally thought youd have something interesting to convey All I hear is a handful of whining about something you could fix in the event you werent too busy trying to find attention
Somebody essentially lend a hand to make significantly posts I might state That is the very first time I frequented your web page and up to now I surprised with the research you made to create this particular put up amazing Excellent job.
I was just as captivated by your creations as I was. The drawing you’ve created is stunning, and the writing you’ve done is sophisticated. However, your remarks indicate that you are worried about the possibility of engaging in something that may be seen as dubious. I’ll be able to resolve this quickly.
Temp Mail Good post! We will be linking to this particularly great post on our site. Keep up the great writing
